DETAILED DESCRIPTION

The present technology is directed to providing security within distributed microservices. The present technology creates secure virtual boundaries around microservices.

In one embodiment, the present technology involves a datacenter, which can be implemented within a cloud. The datacenter includes physical resources such as servers that provide virtual machines. The virtual machines can provide microservice components such as web services, application services, database services, and so forth. In some embodiments, the servers are physically separate from one another within the datacenter.

A microservice is a combination of microservice components selected to facilitate the microservice. An example microservice includes, but is not limited to, a game, an e-commerce application, a media service, and so forth. Because the servers providing the microservice components can be distributed in different physical locations, the microservice is itself distributed because its microservice components may not reside on the same physical server. To be sure, the present technology can manage enforcement points on multiple servers as a single, logical system. Enforcement points are described in related U.S. patent application Ser. No. 14/673,679, filed on Mar. 30, 2015, which is hereby incorporated by reference in its entirety.

In the present technology, the servers and virtual machines are controlled with a host server that coordinates the operations of the distributed microservice components to provide the microservice. The host server includes a director module that manages sessions and settings of the distributed microservice components.

The director module can also instantiate (e.g., “spin up”) a plurality of enforcement points that are configured to create a secure virtual boundary around a set of distributed microservice components for a microservice.

The enforcement points can intercept and measure traffic at locations within the secure virtual boundary, such as traffic entering and exiting the distributed microservice components.

In some embodiments, the director module distributes a security policy, such as a firewall policy to the enforcement points which protect each of the distributed microservice components. The director module can also receive traffic information from the enforcement points and determine network traffic profiles and malicious attacks that are occurring on, or within the secure virtual boundary.

Advantageously, the present technology provides a distributed microservice system where distributed enforcement points are placed in communication with enterprise assets such as microservice components. The enforcement points are configured to correlate information to understand the traffic flows within the secure virtual boundary.

The enforcement points provide a stateful solution by operating as security policy enforcement devices that use stateful inspection engines for analyzing network traffic.

In another advantage, the present technology provides for real-time detection and visualization of threat movement, attack remediation, and exfiltration prevention, as well as microsegmentation and policy enforcement control.

As mentioned above, the present technology provides a data center security solution that protects enterprise data, whether on-cloud or on-premise, with a single virtual security system.

The data center security of the present technology delivers a consistent layer of visibility and control across virtual, cloud and physical applications. Using the present technology, enterprises can understand the progression of an attack and trace its lineage to a “Patient Zero,” a point of entry of an attacker (or the first infected computer). Using the present technology, enterprises have immediate insight into their data center risk profile and are able to adjust security measures without changing existing policies or Information Technology (IT) infrastructures.

Referring now to FIG. 1, a schematic diagram of a data center 100 providing secure microservices that are secured using the present technology is illustrated. In some embodiments, the data center 100 is generally described as a cloud-based computing environment that facilitates services, such as enterprise services. It will be understood that the data center 100 can be utilized to provide any type of service, such as gaming services, email services, e-commerce services, Domain Name System (DNS) services, web hosting services, and so forth.

In general, a cloud-based computing environment is a resource that typically combines the computational power of a large grouping of processors, and/or an environment that combines the storage capacity of a large grouping of computer memories or storage devices. For example, systems that provide a cloud resource may be utilized exclusively by their owners; or such systems may be accessible to outside users who deploy applications within the computing infrastructure to obtain the benefit of large computational or storage resources.

The cloud may be formed, for example, by a network of web servers, such as web servers, with each web server (or at least a plurality thereof) providing processor and/or storage resources. These servers may manage workloads servicing multiple users (e.g., cloud resource customers or other users). Typically, each user places workload demands upon the cloud that vary in real-time, sometimes dramatically. The nature and extent of these variations typically depend on the type of business associated with the user.

The data center 100 is configured to provide microservices to tenants. A microservice will be understood to include a software application (e.g., service) that is comprised of a plurality of independently deployable services, referred to herein as “microservice components.” In some embodiments, the data center 100 comprises a plurality of physical servers (sometimes referred to as racks or blades), such as a first server 102, a second server 104, and a third server 106.

In one embodiment, the first server 102 provides web service microservices that provide a standardized means for integrating web applications using various open standards such as JavaScript Object Notation (JSON), Representational State Transfer (REST), and so forth. As illustrated, the first server 102 comprises a plurality of microservice components such as a first web service 108, a second web service 110, and a third web service 112. Again, the first server 102 can comprise additional or fewer microservice components than those illustrated. Also, the type of web service provided by each of the web service microservice components can be identical or different. For example, the web service microservice components 108-112 can all provide Simple Object Access Protocol (SOAP) services, while in another embodiment each of the web service microservice components 108-112 can provide a unique web service.

The second server 104 comprises a plurality of application microservice components such as the first application (App) 114, the second application 116, and the third application 118. Again, the second server 104 can comprise additional or fewer microservice components than those illustrated. Also, the type of application provided by each of the application microservice components can be identical or different. The applications provided by the application microservice components 114-118 can be identical or different from one another.

The third server 106 comprises a plurality of database microservice components such as the first database 120, the second database 122, and the third database 124. Again, the third server 106 can comprise additional or fewer microservice components than those illustrated. Also, the type of database provided by each of the database microservice components can be identical or different. The databases provided by the database microservice components 120-124 can be identical or different from one another.

The data center 100 also comprises a server host 126 that can be located away from the servers 102-106 so as to reduce the likelihood that the host server will be infected with malware or subject to a malicious attack if any of the servers 102-106 or their microservice components are attacked. The server host 126 can also include a virtual machine server or a physical server. The server host 126 can comprise a director module 128. The director module 128 can comprise executable instructions that are stored in a non-transitory computer readable medium, such as memory of the server host 126. The director module 128 can be executed by a processor of the server host 126 to provide functionalities ascribed to the director module 128 which are described in greater detail below.

As used herein, the term “module,” “controller,” or “device” may also refer to any of an application-specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) that executes one or more software or firmware programs, a combinational logic circuit, and/or other suitable components that provide the described functionality.

The servers 102-106 each provide a microservice type. For example, the microservice type for the first server 102 comprises web services, while a microservice type of the second server 104 is applications, and the microservice type of the third server 106 is database related.

In some embodiments, the data center 100 can comprise additional or fewer servers than those illustrated. Also, the microservices of some of the servers, for example servers 102 and 104, can be combined onto a single physical server but facilitated by a virtual machine. Thus, the web service microservice components 108-112 can be executed using a first virtual machine, while the application microservice components 114-118 can be executed on a second virtual machine. Indeed, the first and second virtual machines can be managed on the same physical server, such as the first or second servers 102 and 104, respectively.

In some embodiments the data center 100 comprises a network 130 that communicatively couples the servers 102-106 and server host 126. Suitable networks may include or interface with any one or more of, for instance, a local intranet, a Personal Area Network (PAN), a Local Area Network (LAN), a Wide Area Network (WAN), a Metropolitan Area Network (MAN), a virtual private network (VPN), a storage area network (SAN), a frame relay connection, an Advanced Intelligent Network (AIN) connection, a synchronous optical network (SONET) connection, a digital T1, T3, E1 or E3 line, Digital Data Service (DDS) connection, Digital Subscriber Line (DSL) connection, an Ethernet connection, an Integrated Services Digital Network (ISDN) line, a dial-up port such as a V.90, V.34 or V.34bis analog modem connection, a cable modem, an Asynchronous Transfer Mode (ATM) connection, or a Fiber Distributed Data Interface (FDDI) or Copper Distributed Data Interface (CDDI) connection. Furthermore, communications may also include links to any of a variety of wireless networks, including Wireless Application Protocol (WAP), General Packet Radio Service (GPRS), Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA) or Time Division Multiple Access (TDMA), cellular phone networks, Global Positioning System (GPS), Cellular Digital Packet Data (CDPD), Research in Motion, Limited (RIM) duplex paging network, Bluetooth radio, or an IEEE 802.11-based radio frequency network.

The network can further include or interface with any one or more of an RS-232 serial connection, an IEEE-1394 (Firewire) connection, a Fiber Channel connection, an IrDA (infrared) port, a SCSI (Small Computer Systems Interface) connection, a USB (Universal Serial Bus) connection or other wired or wireless, digital or analog interface or connection, mesh or Digi® networking.

In some embodiments, individual microservice components from an individual server can be used to facilitate a microservice. For example, a first microservice 132 comprises a game service. The first microservice 132 comprises the second web service 110, the second application 116, and the second database 122. To be sure, these selected microservice components are needed to facilitate the game service.

In various exemplary embodiments, a second microservice 134 comprises an e-commerce service. The second microservice 134 comprises the third web service 112, the third application 118, and the third database 124. To be sure, these selected microservice components are needed to facilitate the e-commerce service.

In sum, the data center 100 is configured to provide a plurality of microservices where each microservice is comprised of a plurality of microservice components.

Cooperative communication between microservice components allows the data center 100 to provide the microservice to a tenant or end user. For example, the second web service 110, the second application 116, and the second database 122 are all communicatively coupled with one another using the network 130.

As mentioned above, the servers that host these microservice components can be positioned remotely from one another. Thus, the microservice components need not be collocated in the same physical server. This physical separation of servers results in physical separation of microservice components for a microservice.

The present technology can provide security policies such as firewall policies that protect these distributed microservices. Rather than directing network traffic to a static firewall or other static appliance, the data center 100 can employ the use of enforcement points, such as enforcement points 136-140 that are disposed within the network communications path of the microservice components of a microservice.

In general, an enforcement point is a virtual or physical module that operates as a security policy enforcement device that uses stateful inspection engines for analyzing network traffic within a secure virtual (e.g., logical) boundary.

An enforcement point can be “spun up” or initiated when a microservice is requested by a tenant or user of the data center 100. For example, if an end user desires to use the first microservice 132 (e.g., a game microservice), the user will request use of the first microservice 132 through the server host 126. The server host 126 will determine which microservice components are needed (in this case the second web service 110, the second application 116, and the second database 122) and will deploy a plurality of enforcement points for the microservice components.

In one embodiment, the data center 100 includes a first enforcement point 136, a second enforcement point 138, and a third enforcement point 140. The first enforcement point 136 is deployed for the first server 102 and the second web service 110. The second enforcement point 138 is deployed for the second server 104 and the second application 116, while the third enforcement point 140 is deployed for the third server 106 and the second database 122. Again, the deployment of the enforcement points is controlled by the director module 128 of the server host 126.

Each of the enforcement points can be placed in network communication with their respective microservice component to intercept and analyze network traffic. In some embodiments, each of the enforcement points analyzes microservice component network traffic by decoding higher-level protocols that create the data stream in software, at “line rate, ” with an acceptable computational cost.

The enforcement points can be deployed near an asset (such as a server or microservice component) to examine precisely the internal and external traffic into that asset (which may be indicative of malicious attacks) or from that asset (indications of infection and internal attacks), and can also be used to provide very granular control (e.g., pass only specific traffic). In some embodiments, the enforcement points comprise logical entities and operate in a global context, the enforcement points can migrate when an asset, such as a microservice component, migrates (e.g., in a virtual environment).

Referring now to FIG. 2, an example enforcement point is illustrated. The enforcement point includes the first enforcement point 136. The first enforcement point 136 comprises a stateful traffic inspection engine(s) 142 that can be used for traffic inspection and/or network traffic control based on security policies received from the director module 128.

Referring now to FIG. 3, which illustrates the distributed nature of the microservice components of FIG. 1. Again, the microservice components required for a particular microservice may be distributed amongst many servers located proximately from one another.

The enforcement points 136-140 can create a logical or virtual security boundary around the microservice components for a microservice. In one example, the enforcement points 136-140 can create a first virtual security boundary 144 around the first microservice 132 (e.g., a game microservice), and specifically the microservice components of the first microservice 132 (the second web service 110, the second application 116, and the second database 122). In another example, the enforcement points 136-140 can create a second virtual security boundary 146 around the second microservice 134 (e.g., an e-commerce service), and specifically the microservice components of the second microservice 134 (the third web service 112, the third application 118, and the third database 124).

While FIG. 1 conceptually illustrates the microservice components for a particular microservice as being aligned, FIG. 3 illustrates a distributed data center where the microservice components for a particular microservice are not strictly aligned. This again is due to the microservice components residing on servers that are distributed throughout the data center 100. Thus, the virtual security boundary created by the enforcement points 136-140 can traverse a meandering path that encloses each of the microservices.

As mentioned above, a set of enforcement points such as enforcement points 136-140, can be used to create a plurality of virtual security boundaries. In other embodiments, a set of enforcement points can be deployed for each microservice. The use of virtual security boundaries also allows for microservices to be logically separated from one another for security purposes.

In FIG. 3, the first enforcement point 136 is positioned in association with microservice components the second web service 110 and the third web service 112. The first enforcement point 136 is positioned into the security boundaries of both the first virtual security boundary 144 and the second virtual security boundary 146. Likewise, the second and third enforcement points 138 and 140 are each positioned into the security boundaries of both the first virtual security boundary 144 and the second virtual security boundary 146.

According to some embodiments, the director module 128 is configured to manage sessions and settings of the distributed microservice components. For example, the director module 128 specifies what microservice components are required for a microservice, when each of the microservice components should be initiated and/or deactivated, and so forth. The director module 128 also determines if additional microservice components should be initiated during microservice use. For example, in a gaming microservice, the director module 128 may increase processing capacity for an application microservice component by initiating one or more additional application microservice component(s). The director module 128 can deploy additional enforcement points if needed to enlarge the virtual security boundary. This type of dynamic virtual security boundary management ensures that the one or more additional application microservice component(s) are protected through inclusion into the virtual security boundary of the gaming microservice. A similar but inverse process can be performed by the director module 128 when microservice components are deactivated.

Also, the director module 128 can track migration of the microservice components and re-deploy the enforcement points. For example, if the first server 102 is taken offline or is no longer functioning, the data center 100 may have backup servers that provide the same microservice as the first server 102. When this backup server comes online, the web service microservice is migrated over to the backup server and the virtual boundary is reconfigured, or the enforcement point is re-deployed. This re-deployment of the enforcement point or reconfiguration of security policy of the enforcement point causes a reconfiguration of the virtual security boundary.

In some embodiments, the director module 128 is configured to implement and distribute security policies for microservices. The security policy may be in accordance with a security profile for a microservice. The security profile can define what types of network traffic anomalies indicate possible malware issues. These traffic anomalies can involve comparisons of network traffic volume over a period of time, network traffic volume at a given period of time, network traffic volume compared to application usage, network traffic input volume versus network traffic output volume, and other similar traffic anomalies.

The director module 128 can selectively control and isolate the network traffic entering and/or exiting any of the microservice components of a microservice, due to the presence of enforcement points with each microservice component. For example, if the network traffic is determined to be anomalous at the second web service 110, the director module 128 can cause the first enforcement point 136 to throttle network traffic into or out of the second web service 110.

Advantageously, the director module 128 can isolate or quarantine a microservice component that appears to be (or actually is) infected with malware or is being subjected to malware attack by providing commands to the enforcement point associated with the microservice component.

Referring now to FIG. 4, a method 400 for providing a logical security boundary for microservices is illustrated. In some embodiments, the method 400 comprises locating 402 a plurality of distributed microservice components that belong to a microservice. In one embodiment, at least a portion of the plurality of distributed microservice components are located on different physical servers in a cloud. In other embodiments, the plurality of distributed microservice components are located on the same server. For example, the director module can be used to determine the location of each distributed microservice component that is used to facilitate a microservice, such as an e-commerce application (e.g., second microservice 134).

The method 400 further includes distributing 404 a plurality of logical enforcement points around the plurality of distributed microservice components that belong to the microservice. For example, the director module can spin up one or more virtual enforcement points (e.g., virtual security appliances) for each distributed microservice component. In some embodiments, virtual enforcement points are positioned both upstream and downstream of each distributed microservice component.

Next, the method 400 comprises forming 406 a logical security boundary from the plurality of logical enforcement points. That is, the virtual enforcement points are communicatively coupled to form a logical security boundary that includes the distributed microservice components.

In some embodiments, the method 400 comprises intercepting 408 by the plurality of logical enforcement points, traffic entering or exiting each of the plurality of distributed microservice components. The method 400 also includes detecting 410 malicious behavior by inspection of the traffic.

In some embodiments, the method 400 includes quarantining 412 any of the distributed microservice components that are found to have anomalous traffic during the inspection process.

Referring now to FIG. 5, which illustrates another example method for implementing a security policy in a distributed manner. To be sure, the method 500 of FIG. 5 can be implemented after deployment of enforcement points throughout a microservice to create a logical security boundary.

In some embodiments, the method 500 includes implementing 502 a security profile for the microservice that includes monitoring traffic within the logical security boundary using the plurality of logical enforcement points.

Next, the method 500 includes comparing 504 the measured traffic to traffic rules included in the security profile. This comparison process can occur at the enforcement point or at the director module.

The method 500 also comprises providing 506 an alert if the traffic within the logical security boundary is indicative of a malicious attack. In some embodiments, the director module can output a message to a system administrator, such as an email or short message service (SMS) message that indicates that a violation of the security profile has occurred.

In some embodiments, the method 500 comprises generating 508 and displaying a visual representation of the traffic within the logical security boundary.

FIG. 6 is a diagrammatic representation of an example machine in the form of a computer system 1, within which a set of instructions for causing the machine to perform any one or more of the methodologies discussed herein may be executed. In various example embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a robotic construction marking device, a base station, a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a cellular telephone, a portable music player (e.g., a portable hard drive audio device such as an Moving Picture Experts Group Audio Layer 3 (MP3) player), a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.

The example computer system 1 includes a processor or multiple processors 5 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), or both), and a main memory 10 and static memory 15, which communicate with each other via a bus 20. The computer system 1 may further include a video display 35 (e.g., a liquid crystal display (LCD)). The computer system 1 may also include an alpha-numeric input device(s) 30 (e.g., a keyboard), a cursor control device (e.g., a mouse), a voice recognition or biometric verification unit (not shown), a drive unit 37 (also referred to as disk drive unit), a signal generation device 40 (e.g., a speaker), and a network interface device 45. The computer system 1 may further include a data encryption module (not shown) to encrypt data.

The drive unit 37 includes a computer or machine-readable medium 50 on which is stored one or more sets of instructions and data structures (e.g., instructions 55) embodying or utilizing any one or more of the methodologies or functions described herein. The instructions 55 may also reside, completely or at least partially, within the main memory 10 and/or within the processors 5 during execution thereof by the computer system 1. The main memory 10 and the processors 5 may also constitute machine-readable media.

The instructions 55 may further be transmitted or received over a network via the network interface device 45 utilizing any one of a number of well-known transfer protocols (e.g., Hyper Text Transfer Protocol (HTTP)). While the machine-readable medium 50 is shown in an example embodiment to be a single medium, the term “computer-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database and/or associated caches and servers) that store the one or more sets of instructions. The term “computer-readable medium” shall also be taken to include any medium that is capable of storing, encoding, or carrying a set of instructions for execution by the machine and that causes the machine to perform any one or more of the methodologies of the present application, or that is capable of storing, encoding, or carrying data structures utilized by or associated with such a set of instructions. The term “computer-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals. Such media may also include, without limitation, hard disks, floppy disks, flash memory cards, digital video disks, random access memory (RAM), read only memory (ROM), and the like. The example embodiments described herein may be implemented in an operating environment comprising software installed on a computer, in hardware, or in a combination of software and hardware.

Not all components of the computer system 1 are required and thus portions of the computer system 1 can be removed if not needed, such as Input/Output (I/O) devices (e.g., input device(s) 30). One skilled in the art will recognize that the Internet service may be configured to provide Internet access to one or more computing devices that are coupled to the Internet service, and that the computing devices may include one or more processors, buses, memory devices, display devices, input/output devices, and the like. Furthermore, those skilled in the art may appreciate that the Internet service may be coupled to one or more databases, repositories, servers, and the like, which may be utilized in order to implement any of the embodiments of the disclosure as described herein.

The present technology involves provisioning vulnerability scanning (or other active probing/packet insertion) along with microsegmentation in a virtualized environment. Microsegmentation is to utilize distributed inline enforcement points to segment and enforce access control of traffic between virtual machines. The present technology can be used to leverage these enforcement points for vulnerability scanning of the virtual machines on a local hypervisor. Advantageously, the present technology improves the performance of a cloud data center with respect to reducing the time of vulnerability scanning of many devices (e.g., VMs of microsegmented environments), allowing vulnerability scans to be run at any time, and allowing vulnerability scanning without any impact to other workloads. These and other advantages of the present technology are described in greater detail herein.

For context, vulnerability scans are performed regularly inside data centers to locate vulnerabilities or misconfigurations of applications/services. Most of the practices are performed from a central location, sending traffic to various microsegments of data center in order to detect if there are any unknown vulnerabilities within any of the virtual machines.

However, there are several issues with current vulnerability scanning processes. For example, vulnerability scanning relies on centralized scanners to scan the entire data center, which is a time intensive process.

The vulnerability scan executes through the entire network to reach the workloads in the data center, which causes disruption of services. Thus, in most data centers, services are taken off line to be scanned due to the time intensiveness of the vulnerability scanning process.

As the vulnerability scanning may affect service availability, the vulnerability scanning can only be done during a scheduled time or overnight when the network traffic is at a minimum. The vulnerability scanning may disrupt all workloads on the networks. There is no way to perform scanning to one or a group of workloads without affecting other adjacent services when using a centrally located vulnerability scanner, because a single vulnerability scanner is scanning every VM in cloud data center. There is no way to scan the workloads (e.g., VM provisioned service or microservice) in a microsegmented environment since all workloads are in their own protected segment.

Stated otherwise, in order to actively probe against each virtual machine, all packets from the probing device (centrally located vulnerability scanner) must traverse the entire network. This limits the number of active probes that can occur at any given time, and can cause network disruption, so workload scanning such as penetration testing and vulnerability scanning are typically done during non-peak times. Each physical interface both on the hypervisor and the network hardware represents a potential choke-point that can cause network disruption and limits the amount of scanning that can occur in parallel. As a result, scanning is often performed in a serialized manner (e.g., hypervisor by hypervisor, with only one hypervisor being scanned at a time). The scanning of a large cloud data center can take days or weeks to perform.

In a microsegmented environment where there is security (e.g., an enforcement point) in front of each VM, scanning can only occur if a security policy has been configured to allow the scanning procedure, making a less secure environment. For example, the vulnerability scan must breach or pass through the network firewall because the VMs require coupling to the centrally located vulnerability scanner in order to complete the vulnerability scanning process.

Additionally, a security device may block some or all of the scanning, giving a false result, which is a security concern.

With the above context in place, the present technology enables vulnerability scanning directly within the microsegmented environments, overcoming the aforementioned deficiencies of a centrally located vulnerability scanner. Microsegmentation deploys an inline enforcement point next to the workloads, on every hypervisor, to monitor or enforce traffic between workloads. The enforcement point can be a virtual machine, a physical server, a kernel module, a process, a container, or an agent inside a server. The workloads can be virtual machines, containers, or physical servers.

In some embodiments, each enforcement point implements an active probe device that performs vulnerability scanning from the enforcement points to the local workloads whenever needed. As the enforcement point is only one hop to the local workloads (e.g., VMs in some embodiments), the enforcement points can scan single or multiple target workloads without any side effects on the neighboring workloads.

Referring now to FIG. 7, a system 700 is illustrated that comprises a cloud data center server 702 and a plurality of microsegmented environments 704A-C. The cloud data center server 702 and plurality of microsegmented environments 704A-C are communicatively coupled to one another over a network 703. In some embodiments, the system 700 is a cloud data center.

It is noteworthy to mention that the plurality of microsegmented environments 704A-C can communicate with a security controller 706 and an active probe controller 708 in a unidirectional manner, meaning that the security controller 706 and the active probe controller 708 can transmit messages to the plurality of microsegmented environments 704A-C such as security policies and vulnerability scanning requests. The plurality of microsegmented environments 704A-C need not transmit data back to the security controller 706 or the active probe controller 708, in some embodiments. This is in contrast with system that implements a centrally located vulnerability scanner where the microsegmented environments depend on the centrally located vulnerability scanner to perform the vulnerability scanning process. When the microsegmented environments 704A-C are adapted to perform vulnerability scanning internally, the plurality of microsegmented environments 704A-C can communicate with the security controller 706 and/or the active probe controller 708 to report a scan status or a security policy violation. Nevertheless, the microsegmented environments 704A-C do not depend on the security controller 706 or the active probe controller 708 to perform a scan. In some embodiments, security controller 706 and the active probe controller 708 may be the same device.

In one embodiment, the cloud data center server 702 comprises the security controller 706 and the active probe controller 708. The cloud data center server 702 can include additional components of a computer system described in greater detail with reference to FIG. 6.

The security controller 706 is configured, in some embodiments to push security policies that are implemented at the hypervisor level or enforcement point level. Examples of security policies include, but are not limited to firewall policies, virus scanning, and well as other security policies that would be known to one of ordinary skill in the art. To be sure, the security controller 706 does not act as a centralized vulnerability scanner because any vulnerability scanning processes occur directly within the microsegmented environments. The security controller 706 can also monitor the microsegmented environments for violation of security policies.

The active probe controller 708 can be utilized to control individual active probe devices executing within the microsegmented environments. The active probe controller 708 can implement execution of scanning schedules or cause vulnerability scanning to occur when potential malicious or suspicious activity, or network traffic, is detected for any workload. For example, the active probe controller 708 can request that an active probe device execute a scan when the security controller 706 detects the violation of a security policy such as the detection of increased network traffic, communication with known malicious resources, or anomalous workload behaviors—just to name a few. To be sure, the active probe controller 708 does not conduct any vulnerability scanning of the microsegmented environments. Again, this scanning occurs entirely within the microsegmented environments.

Additional descriptions of the microsegmented environments are provided below. For brevity and clarity, only one of the microsegmented environments 704A-C, such as microsegmented environment 704A is described in greater detail. Thus, each of the microsegmented environments 704B-C can be implemented in a manner similar to microsegmented environment 704A. To be sure, the system 700 can implement any number of microsegmented environments.

The microsegmented environment 704A comprises a hypervisor 710, an enforcement point 712, an active probe device 716, and a plurality of VMs 714A-C (broadly defined as “workloads” or “microservices” herein).

The hypervisor 710 controls and manages the plurality of virtual machines 714A-C, allowing them to create and provide microservices to end users.

As mentioned above, the enforcement point 712 can be a virtual machine, a physical server, a kernel module, a process, a container, or an agent inside a server. The plurality of virtual machines 714A-C can also include containers or physical servers that are configured to provide microservices or workloads.

Enforcement points are deployed on hypervisors and managed by a director such as the cloud data center server 702. According to some embodiments, the enforcement point 712 comprises an active probe device 716. In general, an active probe device is a component that generates packets to test/check devices that are on the network. Examples of an active probe device include, but are not limited to, a vulnerability scanner, a penetration tester, a host scanning tool, or any other device used for active monitoring or scanning purposes.

In some embodiments, the enforcement point 712 is configured to control the active probe device 716 to execute a vulnerability scan of the plurality of virtual machines 714A-C. In some instances the enforcement point 712 is pre-programmed to cause the active probe device 716 to execute a vulnerability scan according to a schedule. For example, the active probe device 716 will execute a vulnerability scan every hour, day, week, or other time. Advantageously, since the active probe devices are each only required to scan the workloads of one microsegmented environment, the time required to scan the entire system 700 is equal to a time required to scan the largest microsegmented environment.

When a vulnerability scan is required for the entire workload (e.g., all VMs in a microsegmented environment), commands are distributed to all enforcement points using the active probe controller 708.

In some embodiments, vulnerability scanning tools are pre-provisioned on the enforcement point within the active probe device 716, the enforcement point 712 can start scanning the targeted workloads. If the vulnerability scanning tools are not pre-provisioned on the enforcement point, the enforcement point 712 can obtain the vulnerability scanning tools from the active probe controller 708, for example. Again, the duration of the scanning of entire data center will be the longest time taken to scan the largest single hypervisor. This is highly advantageous compared to systems that implement vulnerability scanning tools outside of the microsegmented environment, such as where a vulnerability scanner services many hypervisors in the data center.

In more detail, a vulnerability scan is desired for a logical group of workloads spread among multiple hypervisors or locations. The active probe controller 708 can initiate scanning by sending commands to enforcement points protecting the targeted workloads. Only the enforcement points protecting targeted workloads will engage the scanning to those local targeted workloads.

While the present technology describes the implementation of vulnerability scanning at the enforcement point level, the same mechanism can expand to any activities with active network probing or packet insertion/modification of network traffic. Other examples can be an active performance measurement probe that an enforcement point sends to the cloud data center server 702 to simulate client packets and thereby measure the performance and latency of cloud data center server 702 responses without creating network overhead. Other examples include HTTP header modification to insert banners or customized texts. Distributed enforcement points can perform these tasks in a more scalable way.

Again, advantages are provided when active probes are located on the security device itself (enforcement point) that is providing the microsegmentation. Network probes become distributed, with a lightweight probe sitting on each element of the distributed security device. Additionally, there is no congestion caused on the network 703. Probing does not traverse any security devices, such as firewalls, removing all security strain due to policy lookups.

Probing is controlled from the active probe controller 708, allowing for scanning to become policy driven or triggered. In an additional advantage, security becomes more secure as changes to a security policy (such as a firewall policy) to allow for scanning, are not required, and scanning can occur directly within a VM.

Probing/scanning can occur on each hypervisor in parallel. Scan type probing (vulnerability scanning for example) on the entire environment will take only as long as it takes to scan the largest hypervisor within the data center. Also, scanning can be executed on-demand or triggered at any time without affecting other adjacent workloads. For example, microsegmented environment 704A can be scanned without affecting the performance of microsegmented environment 704B or microsegmented environment 704C.

In yet another advantage, the distributed nature of implementing scanning within the microsegmented environments themselves allows for real-time scanning of the entire data center, even during peak data center hours. This is because the vulnerability scanning occurs at the microsegmented environment level, rather than requiring communication over the network with a centrally located vulnerability. Thus, the distributed nature of the vulnerability scanning of the system 700 causes no deleterious effect whatsoever on network performance, such as latency of the network 703.

In some embodiments, the active probe controller 708 is configured to implement a remediation scheme when a vulnerability scan indicates that a workload/VM is experiencing vulnerability.

In one example, a remediation scheme comprises the enforcement point 712 isolating its microsegmented environment 704A from communicating with other microsegmented environments (e.g. microsegmented environments 704B/704C) or communicating over the network 703.

In another example, a remediation scheme comprises the security controller 706 implementing a heightened security policy for the microsegmented environment 704A. In yet another example, the remediation scheme comprises the enforcement point 712 or the active probe controller 708 identifying a microsegmented environment for further evaluation by a security administrator.

FIG. 8 is a flowchart of an example method 800 for providing vulnerability scanning within a microsegmented data center.

The method 800 includes a step of establishing 802 a plurality of microsegmented environments within a cloud data center. As mentioned above, each of the plurality of microsegmented environments comprises a hypervisor that controls a plurality of virtual machines. Further, each of the hypervisors comprises at least one active probe device that implements vulnerability scanning, for example.

Next, the method 800 includes provisioning 804 each of the plurality of microsegmented environments with a security policy that is implemented by the hypervisor. Again, this security policy can include a firewall policy for the microsegmented environment.

In some embodiments, the method 800 includes executing 806 a vulnerability scan on each of the plurality of microsegmented environments by way of their respective active probe devices. In some embodiments, the scan occurs simultaneous on the plurality of microsegmented environments (e.g., in parallel).

As mentioned above, the step of executing a vulnerability scan can occur at the behest of the enforcement point if the enforcement point is pre-provisioned with a scanning schedule. Alternatively, the step of executing a vulnerability scan can occur when the active probe controller causes the enforcement points (ultimately the active probe devices) to conduct a vulnerability scan.
